CompTIA Cloud+ (CV1-003) — Question 12

A systems administrator needs to configure monitoring for a private cloud environment. The administrator has decided to use SNMP for this task.
Which of the following ports should the administrator open on the monitoring server's firewall?

Answer options

• A. 53
• B. 123
• C. 139
• D. 161

Correct answer: D

Explanation

The correct answer is D, as SNMP uses port 161 for communication. The other ports listed (53, 123, and 139) are associated with different services: port 53 is for DNS, port 123 is for NTP, and port 139 is for NetBIOS sessions, which are not relevant for SNMP monitoring.
